Description

A new Pelican nebula in "narrowband" colour. I took the chance to take a lot of additional frames in H, S and O during the last two nights. It was hard to reach the -20°C sensor temperature due to the warm nights.
I played arround a bit with colour balancing. It is not strictly SHO but a mix of all three for the different colour channels with different mix ratios - just for fun.
